New features and changes

Suggested actions

Suggested actions UI

A new feature called Suggested actions has been introduced, which shows relevant actions when certain kinds of content is selected. When a phone number is selected, a popup offering to call the phone number using Teams or calling apps shows up. Similarly, when a date and/or time is selected, a popup offering to add the date to a supported calendar app will appear. The feature can be toggled by the "Suggested actions" option in Settings under System → Clipboard.

Recovery Environment

The icons shown in the Windows Recovery Environment and the graphical boot menu have been updated to match the Windows 11 design. As a part of this change, the new Windows logo is now properly used for Windows 11 installations while the new icons for Windows 8 and Windows 10 now feature the respective version number inside a window, similarly to the design already used for Windows 7.

Miscellaneous

• The performance of loading Home page in File Explorer has been improved.
• The underlying speech platform has been updated to improve voice activity detection for voice access, live captions, and voice typing, as well as address some issues with how punctuation is recognized.
• This is the first available client build to include the Windows logo banner removal first spotted in Windows Server build 25075. This affects the legacy shutdown dialog shown when pressing Alt+F4 on the desktop, the about dialogs of many built-in apps and the hidden System page in the Control Panel. Interestingly, the Windows logo banner in the hidden System page in the Control Panel was Windows 10 instead of Windows 11.

Shell
